SUBSOILER ATTACHMENT FOR FLOWS.

Application filed May 25, 1920.

T0 all 107mm it may concern Be it known that I, CHARLES XV. FRANCIS, acitizen of the United States, residing at Murfreesboro, in the county ofPike, State of Arkansas, have invented a new and useful subsoilerAttachment for Flows; and I do hereby declare the following to be afull, clear, and eXact description of the invention such as will enableothers skilled in the art to which it appertains to make and use thesame.

T he invention relates to plow attachments and has for its object toprovide an attachment whereby subsoilers carried by plow standard may beeasily and quickly attached to the plow beam without changing thestructure of the plow and also to provide means whereby said plowstandard may be adjusted at various angles and also adjusted so that thesubsoiler shovel carried by the plow standard will make different depthsof cut.

A further object is to provide a subsoiler attachment for plow beams,said subsoiler attachment comprising a bracket which may be easily andquickly attached to the rear bowed portion of the plow beam so that itsarms will extend rearwardly and to provide the rearwardly extending armswith means for receiving and holding a plow standard to which may beattached a subsoiler.

A. further object is to provide avdetaclr' able subsoiler for plowswhich subsoiler is car ed a bracket attached to the plow beam, and to soconstruct the bracket that the subsoiler ii be positioned in variouspositions. With the above and other objects in view the inventionresides in the combination and arrangement f parts as hereinafter setforth, shown in the drawings, described and claimed, it being understoodthat changes in the precise embodiment of the invention may be madewithin the scope of what is claimed without departing from the spiri ofthe invention.

In the drawings Figure 1 is a side elevation of a portion of a plowshowing th subsoiler attached thereto.

Fig. 2 is a perspective view of the subsoiler bracket.

'Fig. 3 is a perspective view of a plow standard showing a doublecolter.

Fig-. 5 isa side elevation f a orti f a plow snowlng a subsoiler carriedby a modihed form of bracket.

Fig. 6 is a detail view showing another form of bracket.

Fig. 7 is a detail view showing another form of bracket.

Referring to the drawings, the numeral 1 designates a conventional formof plow and 2 the beam thereof. Th low beam is of a conventional formand is provided with the bowed ortion 3, to which portion the subsollerbracket is detachably secured. Referring more especially to Figs. 1 and2 it will be seen that the subsoiler supporting bracket l is formed fromtwo members 5, which are secured together as at 6. Members 5 areprovided with U-shaped portions 7, which U-shaped portions have the samecurvature and register with each other and are adapted to receivetherebetween the bowed portions 3 of the plow beam. U-shaped portions 7are provided with transversely disposed bolts 8 and 9, bolts 8 beingdisposed forwardly of the bowed portion 3 and the bolt 9 reaiwvardly.lVhen the bolts 8 and 9 are tightened it will be seen that the bracketl: will be securely clamped on the bowed portion 3 of the plow beam. Oneof the members 5 is bent as at 10 so as to form an engaging shoulderadapted to engage the conveXed rear edge of the bowed portion 3 so as toadditionally hold the bracket as a whole against pivotal action. Members5 are provided with oppositely extending curved arms ll and 12, whicharms terminate in substantially parallel portions 13 and 1 1-, whichportions are bent so as to form U- shaped members 15 for the receptionof the plow standard 16, said plow standard being held in place by meansof the jam wedges 1?, said wedges forming means whereby the plowstandard may be held in various positions. Plow standard 16 extendsdownwardly at a point to the rear of the plow beam and is provided witha subsoiler shovel 18, which subsoiler shovel may be of anv form, if sodesired it may be a triple colter 19 as shown in Fig. 3 or a doublecolter 20 as shown in Fig. 4.

From the above it will be seen that a bracket is provided which may beeasily and quickly attached to a plow beam in such a manner that it willsupport a subsoiler plow standard at various angles and that thesubsoiler shovel 18 may be achusted to take various depths of cuts. Itwill also be seen that the bracket may be attached to any conventionalform of plow without changing the structure of the plow.

Referring to the form shown in Fig. 5 it will be seen that the bracket icomprises a member 21 having a U-shaped portion 23 which is clampedandheld on the bowed portion 3 of the plow beams 2 by means of a U-bolt24 and a bolt 25, which passes through the portion 3 of the plow beam.Member 23 extends rearwardly and is provided with a shoulder 26 adaptedto engage the rear convened edge of the bowed portion 3 and beyond whichshoulder 26 the member is provided with an arm 28, to the rear end ofwhich is secured by means of a bolt 29 to a plow standard 30, which maycarry a plurality of cultivator shovels 82. Plow standard 30 is providedwith a plurality of apertures 31, through any one of which the bolt 29may pass for holding the plow standard at different distances from theground ac cording to the depth of cut desired. The

7 arm 28 is provided with a series of apertures 33, which apertures maybe placed in registration with any of the apertures 31 so that the plowstandard 30 may be adjusted to various angles. Secured to the member 21as at 34: is a seg entally shaped plate 35, the lower end of said platebeing provided with a series of. apertures 36 which apertures may beplaced in registration with any of the apertures 33 when it is desiredto change the angleof the plow standard 30. The upper end of the plate35 is secured to the plow standard 30 by means of a-bolt 37 which passesthrough one of the apertures 38 and one of the apertures 31. t will beseen that the member 21 is securely fastened to the bowed portion 0 andthat the plow standard may be adjusted at various angles and it also maybe adjusted to various positions upwardly and downwardly.

Referring to F 6, it will be seen that the bracket 4 comprises aU-shaped member 38 having rearwardly extending arms 39, said arms beingprovided with apertures so that the plow standard 30 may be adjustablyattached thereto. The il -shaped member 38 being held on bowed portion 3of the plowby means of straps d0 which arch the plow beam and may beadjusted to various positions by means of the bolts 41 and apertures l2.

Referring to Fig. 7 it will be seen that the structure ispractically'the same as that shown in Fig. 6 except that instead of thearm 39 at the upper side of the U-shaped member 8, said arm 59 is cutoff and an angularly disposed brace bar 43 is provided. Brace bar 43 isprovided with a series of apertures 4a, which apertures are adapted toregister with anyone of the apertures 45 in the plow standard 30. Thelower end of the bar 33 being secured to the arm 39 as at 46 and may beadditionally secures to said arm by means of a bolt 47. Arm 89 isprovided with a series of apertures e8, anyone of which may be placed inregistration with anyone of the apertures as of the plow standard 30 andmay be secured thereto by means of a bolt 50.

From the above it will be seen that subsoiler attachment for plow beamsis provided which may be easily and quickly attached to any conventionalform of plow beam and it will also be seen that an attach ment of thischaracter is provided which may be adjusted for different depths of cutsand at different angles.

The invention having been set forth what is claimed as new and useful isThe combination with a plow having a beam provided with a rear bowedportion, of a subsoiler therefor, said subsoiler con prising a plowstandard having a subsoilinp' element, a bracket carried by the bowedportion of the plow beam, said bracket comprising two members, theforward ends of said members being provided with similarly shapedU-shaped member, said .iJ-shaped members extending forwardly, upwardlyand rearwardly and adapted to engage the sides of the bowed portion ofthe plow beam, securing means passing through said U- shaped members anddisposed forwardly and rearwardly, of the bowed edges of the plow beam,said Ushaped portions into upwardly and rearwardly extending arms,bearings in said arms for the reception of the plow standard, and meanspassing through said arms for holding the plow standard in variouspositions.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
